I needed to get longer Wheel Studs in order to pass tech for the pro star wheels at IDRC so I got the Nismo 60 mm Hub Bolts and they worked great, however when changing back to street tires I shaved off 4 of the bolts, I guess the Closed Weld Lug Nuts are just a bit too short and since no one seems to make 12x1.25 mag lug nuts that are open ended I'm hoping that maybe ARP makes Wheel Studs that don't break every time I change my tires since this is getting really expensive.

Long story short:

Anyone know the dimensions that I need to give ARP in order to find out if they make a stud that fits the rear wheel hubs on the Z.

also is it possible to replace the 12x1.25 with a 12.1.5 on the Z which would solve the stupid lug nut problem?

Help is appreciated
